Cisco XR 12406 Router Installation Guide

•
Keep your back straight and lift with your legs, not your back. If you must
bend down to lift the equipment, bend at the knees, not at the waist, to reduce
the strain on your lower back muscles.
•
Always disconnect all external cables before lifting or moving the router.
Safety with Electricity
Most Cisco XR 12406 router field replaceable units (FRUs) support online
insertion and removal (OIR), which means they can be removed and installed
(hot-swapped) while the router remains powered on.
•
Line cards, switch fabric cards (SFCs), alarm cards, and the blower module
are hot-swappable.
•
Power modules, clock and scheduler cards (CSCs), and RPs also support OIR,
but are hot-swappable only when the system is equipped with two power
modules, two CSCs, or two RPs, respectively.
•
The power distribution unit (PDU) does not support OIR.
